Further, the range ofthe aberration offset for the view of image formation may be limited to50%-100% field. An offset of the spherical aberration is denoted by DFS.An offset of the coma aberration is denoted by DFC.

A modulation transfer function (MTF) graph of an optical image capturingsystem is used to test and evaluate the contrast and sharpness of thegenerated images. The vertical axis of the coordinate system of the MTFgraph represents the contrast transfer rate, of which the value isbetween 0 and 1, and the horizontal axis of the coordinate systemrepresents the spatial frequency, of which the unit is cycles/mm orlp/mm, i.e., line pairs per millimeter. Theoretically, a perfect opticalimage capturing system can present all detailed contrast and every lineof an object in an image. However, the contrast transfer rate of apractical optical image capturing system along a vertical axis thereofwould be less than 1. In addition, peripheral areas in an image wouldhave poorer realistic effect than a center area thereof has. For visiblespectrum, the values of MTF in the spatial frequency of 55 cycles/mm atthe optical axis, 0.3 field of view, and 0.7 field of view on an imageplane are respectively denoted by MTFE0, MTFE3, and MTFE7; the values ofMTF in the spatial frequency of 110 cycles/mm at the optical axis, 0.3field of view, and 0.7 field of view on an image plane are respectivelydenoted by MTFQ0, MTFQ3, and MTFQ7; the values of MTF in the spatialfrequency of 220 cycles/mm at the optical axis, 0.3 field of view, and0.7 field of view on an image plane are respectively denoted by MTFH0,MTFH3, and MTFH7; the values of MTF in the spatial frequency of 440cycles/mm at the optical axis, 0.3 field of view, and 0.7 field of viewon the image plane are respectively denoted by MTF0, MTF3, and MTF7. Thethree aforementioned fields of view respectively represent the center,the inner field of view, and the outer field of view of a lens, and,therefore, can be used to evaluate the performance of an optical imagecapturing system. If the optical image capturing system provided in thepresent invention corresponds to photosensitive components which providepixels having a size no large than 1.12 micrometer, a quarter of thespatial frequency, a half of the spatial frequency (half frequency), andthe full spatial frequency (full frequency) of the MTF diagram arerespectively at least 110 cycles/mm, 220 cycles/mm and 440 cycles/mm.

If an optical image capturing system is required to be able also toimage for infrared spectrum, e.g., to be used in low-light environments,then the optical image capturing system should be workable inwavelengths of 850 nm or 800 nm. Since the main function for an opticalimage capturing system used in low-light environment is to distinguishthe shape of objects by light and shade, which does not require highresolution, it is appropriate to only use spatial frequency less than110 cycles/mm for evaluating the performance of optical image capturingsystem in the infrared spectrum. When the aforementioned wavelength of850 nm focuses on the image plane, the contrast transfer rates (i.e.,the values of MTF) in spatial frequency of 55 cycles/mm at the opticalaxis, 0.3 field of view, and 0.7 field of view on an image plane arerespectively denoted by MTFI0, MTFI3, and MTFI7. However, infraredwavelengths of 850 nm or 800 nm are far away from the wavelengths ofvisible light; it would be difficult to design an optical imagecapturing system capable of focusing visible and infrared light (i.e.,dual-mode) at the same time and achieving certain performance.

The present invention provides an optical image capturing system, inwhich the fifth lens is provided with an inflection point at theobject-side surface or at the image-side surface to adjust the incidentangle of each view field and modify the ODT and the TDT.

where f is a focal length of the optical image capturing system; HEP isan entrance pupil diameter of the optical image capturing system; HOS isa distance between an object-side surface, which face the object side,of the first lens and the image plane on the optical axis; InTL is adistance from the object-side surface of the first lens to theimage-side surface of the fifth lens on the optical axis; HAF is a halfof a maximum view angle of the optical image capturing system; HOT is amaximum height for image formation perpendicular to the optical axis onthe image plane; ETL is a distance in parallel with the optical axisbetween a coordinate point at a height of 1/2 HEP on the object-sidesurface of the first lens and the image plane; EIN is a distance inparallel with the optical axis between the coordinate point at theheight of 1/2 HEP on the object-side surface of the first lens and acoordinate point at a height of 1/2 HEP on the image-side surface of thefifth lens.

For any lens, the thickness at the height of a half of the entrancepupil diameter (HEP) particularly affects the ability of correctingaberration and differences between optical paths of light in differentfields of view of the common region of each field of view of lightwithin the covered range at the height of a half of the entrance pupildiameter (HEP). With greater thickness, the ability to correctaberration is better. However, the difficulty of manufacturing increasesas well. Therefore, the thickness at the height of a half of theentrance pupil diameter (HEP) of any lens has to be controlled. Theratio between the thickness (ETP) at the height of a half of theentrance pupil diameter (HEP) and the thickness (TP) of any lens on theoptical axis (i.e., ETP/TP) has to be particularly controlled. Forexample, the thickness at the height of a half of the entrance pupildiameter (HEP) of the first lens is denoted by ETP1, the thickness atthe height of a half of the entrance pupil diameter (HEP) of the secondlens is denoted by ETP2, and the thickness at the height of a half ofthe entrance pupil diameter (HEP) of any other lens in the optical imagecapturing system is denoted in the same manner. The optical imagecapturing system of the present invention satisfies:0.3≤SETP/EIN<1;

where SETP is the sum of the aforementioned ETP1 to ETP5.

In order to enhance the ability of correcting aberration and to lowerthe difficulty of manufacturing at the same time, the ratio between thethickness (ETP) at the height of a half of the entrance pupil diameter(HEP) and the thickness (TP) of any lens on the optical axis (i.e.,ETP/TP) has to be particularly controlled. For example, the thickness atthe height of a half of the entrance pupil diameter (HEP) of the firstlens is denoted by ETP1, the thickness of the first lens on the opticalaxis is TP1, and the ratio between these two parameters is ETP1/TP1; thethickness at the height of a half of the entrance pupil diameter (HEP)of the first lens is denoted by ETP2, the thickness of the second lenson the optical axis is TP2, and the ratio between these two parametersis ETP2/TP2. The ratio between the thickness at the height of a half ofthe entrance pupil diameter (HEP) and the thickness of any other lens inthe optical image capturing system is denoted in the same manner. Theoptical image capturing system of the present invention satisfies:0<ETP/TP≤5.

The horizontal distance between two neighboring lenses at the height ofa half of the entrance pupil diameter (HEP) is denoted by ED, whereinthe aforementioned horizontal distance (ED) is parallel to the opticalaxis of the optical image capturing system, and particularly affects theability of correcting aberration and differences between optical pathsof light in different fields of view of the common region of each fieldof view of light at the height of a half of the entrance pupil diameter(HEP). With longer distance, the ability to correct aberration ispotential to be better. However, the difficulty of manufacturingincreases, and the feasibility of “slightly shorten” the length of theoptical image capturing system is limited as well. Therefore, thehorizontal distance (ED) between two specific neighboring lenses at theheight of a half of the entrance pupil diameter (HEP) has to becontrolled.

In order to enhance the ability of correcting aberration and to lowerthe difficulty of “slightly shorten” the length of the optical imagecapturing system at the same time, the ratio between the horizontaldistance (ED) between two neighboring lenses at the height of a half ofthe entrance pupil diameter (HEP) and the parallel distance (IN) betweenthese two neighboring lens on the optical axis (i.e., ED/IN) has to beparticularly controlled. For example, the horizontal distance betweenthe first lens and the second lens at the height of a half of theentrance pupil diameter (HEP) is denoted by ED12, the horizontaldistance between the first lens and the second lens on the optical axisis denoted by IN12, and the ratio between these two parameters isED12/IN12; the horizontal distance between the second lens and the thirdlens at the height of a half of the entrance pupil diameter (HEP) isdenoted by ED23, the horizontal distance between the second lens and thethird lens on the optical axis is denoted by IN23, and the ratio betweenthese two parameters is ED23/IN23. The ratio between the horizontaldistance between any two neighboring lenses at the height of a half ofthe entrance pupil diameter (HEP) and the horizontal distance betweenthese two neighboring lenses on the optical axis is denoted in the samemanner.

The horizontal distance in parallel with the optical axis between acoordinate point at the height of 1/2 HEP on the image-side surface ofthe fifth lens and image surface is denoted by EBL. The horizontaldistance in parallel with the optical axis between the point on theimage-side surface of the fifth lens where the optical axis passesthrough and the image plane is denoted by BL. In order to enhance theability to correct aberration and to preserve more space for otheroptical components, the optical image capturing system of the presentinvention can satisfy: 0.1≤EBL/BL≤1.5.

The optical image capturing system can further include a filteringcomponent, which is provided between the fifth lens and the image plane,wherein the horizontal distance in parallel with the optical axisbetween the coordinate point at the height of 1/2 HEP on the image-sidesurface of the fifth lens and the filtering component is denoted by EIR,and the horizontal distance in parallel with the optical axis betweenthe point on the image-side surface of the fifth lens where the opticalaxis passes through and the filtering component is denoted by PIR. Theoptical image capturing system of the present invention can satisfy:0.1≤EIR/PIR≤1.1.

In an embodiment, a height of the optical image capturing system (HOS)can be reduced while |f1|>f5.

In an embodiment, when the lenses satisfy f2|+|f3|+|f4| and |f1|+|f5|,at least one lens among the second to the fourth lenses could have weakpositive refractive power or weak negative refractive power. Herein theweak refractive power means the absolute value of the focal length ofone specific lens is greater than 10. When at least one lens among thesecond to the fourth lenses has weak positive refractive power, it mayshare the positive refractive power of the first lens, and on thecontrary, when at least one lens among the second to the fourth lenseshas weak negative refractive power, it may fine tune and correct theaberration of the system.

In an embodiment, the fifth lens could have negative refractive power,and an image-side surface thereof is concave, it may reduce back focallength and size. Besides, the fifth lens can have at least an inflectionpoint on at least a surface thereof, which may reduce an incident angleof the light of an off-axis field of view and correct the aberration ofthe off-axis field of view.

In addition, the opposite surfaces (object-side surface andimage-side surface) of the first to the fifth lenses could be asphericthat can obtain more control parameters to reduce aberration. The numberof aspheric glass lenses could be less than the conventional sphericalglass lenses, which is helpful for reduction of the height of thesystem.
